I would like to know how to debug this. I have two 4 disk enclosures:
Mediasonic ProBox 4 Bay 3.5' SATA HDD Enclosure USB 3.0 & eSATA (HF2-SU3S2)
NexStar HX4 - NST-640SU3-BK
and both have 4 disk on them, and not all disk are equal.
The issue comes when I plug the probox usb3 enclosure on the system. I
can't even read the /var/log/message, it crashes very quickly.
I can see on the boot process up to the point where the second enclosure
comes to be loaded. The 4 disk are shown on the dmesg/console, and then a
core dump happens, the boot process goes to the debug screen and a restart
happens like a flash.
The motherboard is a Intel® Desktop Board D525MW running 8GB RAM.
All disk use ZFS, 4 or 5 zpools, one raidz, one mirror and two or three
single disk pools.

The kernel is a slightly modified generic, just to have altq.
How can I debug this? I have no idea. I have to use two machines to run
all those disks, and I would really like to have just one for it.
Can it be the amount of RAM? The other box is and APU2 from PCEngines and
have 4GB ram. apu2 uname -a: FreeBSD yyy 11.1-RELEASE-p4 FreeBSD

I tried to plug the Vantec hardware on the apu2 box, but there it would
not panic, but won't load all vantec disks neither. I really run out of
ideas here :(
